Re: Buzzing relay... 166 sportivo 2002
the throttle is fly -by-wire system , no cable going to the throttle body from the accelerator pedal...there is a motor opening and closing the throtttle . if you put the ignitition on you can hear a buzz sound, thats normal, its just that motor.
The climate control messages might be that the fan motor is going, not very easy to replace and expensive job if you take the car in . i have 2 of them motors as well £50 , anyway i hope its not that because its such a PITA to replace
